There are two economic sources of lithium; brines and hard rock ores. The majority of the global lithium production, greater than 60%, is produced from brines while lithium ores accounted for the remaining production (Ebensperger et al., 2005).Table 1 summarises the world's major lithium producers from ores and brines, and the total …
The objectives of the framework are to enhance mineral beneficiation and value addition, promote sustainable socioeconomic development, and create economic opportunities for local communities.

Industrial evaluation based on results of chemical analysis shows that the limestone meets the specifications for a batch material in cement production, particularly after beneficiation.
Lithium minerals are usually associated with gangue minerals, such as quartz and feldspar, so the content of lithium oxide in the ore is low. These useful components are enriched through beneficiation to obtain lithium concentrate, which usually includes gravity separation, magnetic separation, flotation, and other processes (Tadesse B et al., …
